Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Images captured by handheld electronic devices with camera modules often suffer from poor quality due to jitters during photographing.
Innovation Solution
A camera module design featuring a first and second module housing, a first bracket, rotating members, and a driving mechanism that allows the camera body to rotate around multiple axes, compensating for hand jitter through multi-axis stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera module is used for handheld photographing, then the camera function is implemented, but image quality deteriorates due to hand jitters
Solution Approach 1:
The patent implements a multi-axis gimbal stabilization system that dynamically adjusts the camera body's orientation in real-time. The gimbal mechanism includes multiple rotating members with adjustable angles around different axes, allowing the system to continuously counteract hand jitter movements and maintain stable image capture during handheld operation
Solution Approach 2:
The gimbal mechanism serves as an intermediary between the camera body and the handheld device. This intermediate stabilization system absorbs and compensates for hand jitter through its multi-axis rotation capability, isolating the camera body from the harmful vibrations and movements of handheld operation
2Adaptability or versatility
If the camera body is fixed in position, then the structure is simple, but the field of view is limited
Solution Approach 1:
The patent employs a dynamic gimbal system with multiple rotating members that can adjust the camera body's orientation around different axes. This dynamic structure enables the camera to capture images at various angles and directions, significantly expanding the field of view while maintaining a relatively compact form factor through coordinated rotation of the rotating members
3Reliability
If a gimbal mechanism is added to stabilize the camera, then image stabilization is improved, but the device complexity increases
Solution Approach 1:
The gimbal stabilization system is divided into multiple independent rotating members, each responsible for stabilization around a specific axis. This segmentation allows the complex stabilization function to be broken down into manageable modular components, facilitating easier assembly, maintenance, and control while achieving comprehensive multi-axis image stabilization

AI summary
Provided are a camera module and an electronic device. The camera module includes a first module housing, a second module housing, a first bracket, a first rotating member, a second rotating member, a third rotating member, a driving mechanism, and a camera body. The camera body is connected to the first module housing through the first bracket, the first rotating member is between the first bracket and the camera body, and the driving mechanism may drive, through the first rotating member, the camera body to rotate around a first axis. The second rotating member is between the first bracket and the first module housing, and the driving mechanism drives the first bracket to rotate. The first module housing is rotatably connected to the second module housing through the third rotating member, and the driving mechanism may drive, through the third rotating member, the first module housing to rotate.
